Measurement of the ratio of B+c branching fractions to J/ψπ+ and J/ψμ+νμ final states
(American Physical Society, 2014-08-27)
The first measurement that relates semileptonic and hadronic decay rates of the B+c meson is performed using proton-proton collision data corresponding to 1.0 fb−1 of integrated luminosity collected ...
Measurement of the fragmentation fraction ratio f s /f d and its dependence on B meson kinematics
(Springer, 2013-04-02)
The relative production rate of B0s and B 0 mesons is determined with the hadronic decays B0s→D−sπ+ and B 0 → D − K +. The measurement uses data corresponding to 1.0 fb−1 of pp collisions at a centre-of-mass ...
Measurement of CP observables in B 0 → DK ∗0 with D →K + K −
(Springer, 2013-03-12)
The decay B 0 → DK *0 and the charge conjugate mode are studied using 1.0 fb−1 of pp collision data collected by the LHCb experiment at s√=7 TeV in 2011. The CP asymmetry between the B 0 → DK *0 and the ...
Production of J/ψ and Υ mesons in pp collisions at s√=8 TeV
(Springer, 2013-06-14)
The production of J/ψ and Υ mesons in pp collisions at s√=8 TeV is studied with the LHCb detector. The J/ψ and Υ mesons are reconstructed in the μ + μ − decay mode and the signal yields are determined ...
Precision measurement of D meson mass differences
(Springer, 2013-06-17)
Using three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The ...
Study of η − η′ mixing from measurement of B 0(s) → J/ψη(′) decay rates
(Springer, 2015-01-08)
A study of B and Bs meson decays into J/ψ η and J/ψ η′ final states is performed using a data set of proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, collected by the LCHb experiment ...
Study of forward Z + jet production in pp collisions at s√ = 7 TeV
(Springer, 2014-01-09)
A measurement of the Z(→ μ + μ −) + jet production cross-section in pp collisions at a centre-of-mass energy s√ = 7 TeV is presented. The analysis is based on an integrated luminosity of 1.0 fb−1 recorded ...
Exclusive J/ψ and ψ(2S) production in pp collisions at √s= 7 TeV
(IOPscience, 2013-02)
Exclusive J/ψ and ψ(2S) vector meson production has been observed in the
dimuon channel using the LHCb detector. The cross-section times branching
fractions to two muons with pseudorapidities between ...
Study of B0(s)→K0Sh+h′− decays with first observation of B0s→K0SK±π∓ and B0s→K0Sπ+π−
(Springer, 2013-10-22)
Measurement of the B+c meson lifetime using B+c→J/ψμ+νμX decays
(Springer, 2014-05-01)
The lifetime of the B+c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb −1, are collected by the ...
